Application filed March 16, 1918. Serial No. 922,}ENJG. i

To all whom it may concern Be it known that I, ORoN K. SKiDMoRn, a citizen of the United States of America, residing at Penns Grove, in the county of Salem and State of New Jersey, have invented new and useful Improvements in Concrete-Steel Ties, of which the following is a specification.

Theinventionrelates to improvements in railroad ties made from concrete and partially surrounded by steel.

. Its principal object is to provide a tie of this character in which two channel members are employed and held in spaced re1ation by suitable connecting means, the space between the two channel members being filled with cement or concrete.

A further object of the invention is to provide a rail engaging means for such a tie, whereby the rail may be securely held in place thereomthe rail engaging means comprising members adapted to engage the base flanges of'the rail and to pass through the i web of one of the channel members and to engage locking devices therebeneath, the locking devices being appropriately embedded in the concrete. r

A still further object provides for making the locking devices removable.

A still further object is to provide a tie of this character which is simple and cheap in construction but yetdur'able and effective in operation. v r i Still further and dther objects will appear as the invention is set forth in detail in the description which follows.

To the. exact embodiment in which it is shown and described, the invention is not to be restricted. Actual practical application may make manifest certain desirable changes or alterations and the right is claimed to make any which do not deviate from the scope of the subjoined claims.

In the accompanying drawings:

Figure 1 is a longitudinal sectional view of the improved tie and portions of rail sections mounted thereon.

Fig. 2 is a section on a line 22 of Fig. 1.

Fig. 3 is a top plan view of a portion of the improved tie.

Fig. 4 is a perspective view of one of the washers used in conjunction with the rail attaching bolts.

In the drawings, the improved tie is shown as comprising channel portions 1 and 2 which are held in spaced relation to each other by appropriate tubular spacing'members 3'. The spacingniembers obtain centrally with respect to the width ofthe channel members and one of said spaoingmem hers is medially disposed with reference to the length of the channel members, while the other spacing members are positioned at appropriate distances from theends of the channel members. Bolts 43 pass through the two channel members and through the spaces and serve to hold all of these parts rigidly connected together.

The space between the two channel members is appropriately filled withconcrete or cement,thereby forming a solid tie with a cross sectional area whoseone dimension is the width of the channel members and whose other dimension is the distance between the upper and lowerfaces of the two channel members. The channel members are, of course, so connected together that their flanges are directed toward eachother.

In the webof thechannel member 1 there are provided. holesfti which are elongatedin the direction of the lengthof-thechannel member. These holes areprovidedforthe purpose of permitting the rail attaching bolts"? to .passthrough them. Theholes 6 are arranged in pairs, one pair on either side of the longitudinal center of the channel member and at such a distance therefrom thatthe two mile 8 may be appropriately attached to the tie, so that the specified regulation distance mayobtain between the edges of the treads of the two rails. One ofthe holes G of each pair: is positioned closerto the longitudinal center ofthech'annel mem berthan "the other of that pairand the two holes of each pair are diagonally disposed with reference to each other, theone being near one flange of the channel member and the other near the other flange of the channel member. The holes are elongated to facilitate the removal ofthe rails without the complete detaching of the rail bolts from their attendant looking devices.

The tie is formed with tapering blocks 9 set in the concrete so that their thinner ends lie below the holes 6 and their thicker ends lie flush with the flanges of the channel member, which together with the concrete or cement form the sides of the tie. The blocks 9 are inclined with reference to. the web of the channel member 1 and the concrete 5 is cast or molded around it. Each block 9 is provided with a hole registering with the hole '6 just above the blockand this hole is broached from the under face of the block leaving a pocket 10 which is adapted to loosely receive the nut 11, the shape of the pocket conforming to the shape of the nut which it receives.

v The rails-8 areattached to the tie after their baseflanges have been positioned on top of the channel member 1, the bolts 7 effecting this attachment in conjunction with washers 12. Thesewashers 12 are circular inplan and are provided with concentric body holes for the bolts 7. The top and bottom faces of the washers are parallel for the most part, but these washers are adapted to lie upon the base flanges of the rail and, therefore, that portion of the under face which engages the tie is beveled off to the angle conforming to the angle which the top face of the flange forms with the bottom face thereof.

The=bolts 7 are adapted to be threaded I into the nuts 11 carried in the pockets 10 of the blocks 9 and when these bolts are firmly. screwed down, after the washers 12 have been attached to them, the rails 8 are firmly heldin place, since the nuts 11 will I I s be drawn up against the tops of the pockets and the washers 12 drawn down on top of the rail flanges.

In the event that any bolt 7 should become sheared off, so that it could not be readily detached from its attendant nut 11, the block 9 connected with the damaged bolt may be easily remo'vel from the tie and such damaged bolt and, its attendant nut conv'eniently removed. The operation for re- 7 moving the block 9 consists only in placing a punch or broach through the hole 6 and having it impinge upon a. portion of the block. The operation of driving upon the punch then serves to release the block from the tie, the taperingshape and diagonal position of the former rendering its removal easy after it has been once loosened.

. As before stated the elongated holes 6 permit the removal of the rails, when it is Copies of this patent may be obtained for so desired, by the loosening of the bolts 7 without the complete detaching from the nuts 11, as the bolts 7 having once been loosened may be shifted to bring their heads and the beveled portions of the washer 12 out of the way of the rails 10.

The foregoing description taken in conjunction with the drawings makes all of the features of the invention apparent and further description is therefore unnecessary.

The invention having been described what is claimed as new and useful is:

1. In a railroad tie, the combination with a solid tie having holes formed in the upper face thereof, of members embedded in the tie and removable therefrom, whereby rail securing devices may be inserted through the holes and engaging with said members.

2. The combination of a solid tie having holes formed in the upper face thereof, with tapering shaped blocks embedded in the tie and diagonally disposed and provided with holes registering with the holes in the tie, the said holes in the blocks being broached from the bottom face thereof to conform to the shape of a nut, whereby rails may be attached to the tie by means of the use of bolts and their attendant nuts.

3. The combination of a concrete steel tie formed of two channel members in spaced relation and containing concrete between them and having means for attaching the channel members together, with tapering blocks set in the concrete so that the thinner ends of the blocks lie against the web of one of the channel members and the thicker edges of the blocks lie flush with the flanges thereof, the said channel members and the blocks being provided with elongated holes, the holes in the blocks being broached from the underface of the blocks to conform to the shape of a nut, whereby rails may be attached to the tie by means of appropriate bolts and their attendant nuts.

In testimony whereof I afiix my signature.
